Definitions

  • This invention relates to a caulking machine.
  • the current construction process for aluminium window and door frames includes technical operations that are now consolidated, consisting of a sequence of machinings on a linear aluminium profile until the finished product is obtained.
  • Window and door frames are typically comprised of a shutter and a frame to which the shutter is hinged.
  • the longitudinal and transverse elements that define the frame and the shutter frame are cut from one or more profile bars with the ends cut at an angle of 45 degrees, depending on the specific lengths corresponding to the measures of the frame.
  • the transverse and longitudinal elements are then coupled together using coupling brackets.
  • This coupling operation is usually referred to as caulking of the linear elements. It involves inserting a bracket through the ends of the two adjacent elements to be joined and special tools are then used to deform part of each of said profiles so as to prevent said bracket from slipping out from said elements, thus locking them integrally.
  • said part of each of said profiles can be deformed or upset, or else partially trimmed or folded, to ensure that it adheres to a surface defining said bracket.
  • machines that include a pair of machining heads and a V-shape backing element, into which the vertex defined by said elements drawn together is inserted, said elements allowing the simultaneous caulking on both adjacent elements to be joined.
  • the object of the present invention is a caulking machine that, according to claim 1, includes a flat frame, an arched frame connected integrally to said flat frame, a V-shaped backing element, a first head and a second head slidingly associated along said flat frame, the position of said V-shaped backing element and of said heads being adjusted in relation to said arched frame by means of first and second thrusting means coordinated by means of motion transmission means.
  • a caulking machine according to the present invention includes a pair of machining heads and a V-shaped backing element supported by a frame and driven simultaneously by appropriate motion transmission means.
  • said motion transmission means include at least one belt that, using appropriate means of transmission, transmits motion from one head to the other and to the V-shaped supporting element, causing the synchronised and coordinated motion of the three elements.
  • a caulking machine 1 includes a flat frame 2, an arched frame 21 connected integrally to the flat frame, a first head 10 and a second head 10' connected to said flat frame so that they can move forwards and backwards in relation to the door or window frame to be caulked.
  • the forward and backward motion of the heads is relative to said arched frame 21, by means of thrusting means 5 and 5' that can be operated manually using a hand wheel 6, or by means of an actuator with position control.
  • Said thrusting means 5 and 5' are preferably endless screws.
  • said hand wheel 6 not only determines the forward or backward motion of the caulking head 10, but also, by means of a belt 3, the forward or backward motion of the caulking head 10'.
  • the belt is not a dual-stage belt, then to move the heads forward, it is necessary to turn the hand wheel 6 indirectly connected to the first head 10, while to move the heads backwards, it is necessary to turn the hand wheel 6' connected indirectly with the second caulking head 10'.
  • Each endless screw system includes a corresponding pulley along which slides said belt 3, which is appropriately moved by means of common transmission means 7 and tighteners 8.
  • Said belt 3 therefore connects the endless screw systems 5 and 5' and a third endless screw system 5" adapted to enable the coordinated forward and backward motion of a V-shaped backing element 4.
  • the pitch of the thread of the third endless screw 5" relative to the V-shaped backing element 4 should have a ratio equivalent to the square root of 2 with respect to the pitch of the thread of the other two endless screws relative to heads 10 and 10'.
  • said third endless screw 5" instead of a corresponding pulley, there may be provided two distinct reels on which to wind, separately and in opposite directions, the portion of the belt that engages the pulley corresponding to the first endless screw 5 and the portion of the belt that engages the pulley corresponding to the second endless screw 5'.
  • each of the heads 10 and 10' includes a thrusting slide 11 adapted to be attached on the bottom to said flat frame 2, by means of fastening means 11a.
  • a caulking assembly 12 is fastened on said thrusting slide 11 in order to slide thereover in the direction imposed by the axis of thrust 14, which is adapted to be connected coaxially to said endless screw system 5, and by a sliding coupling including slides 15 that limit the mutual motion between the caulking assembly and the thrusting slide.
  • This actuator preferably of a hydraulic or pneumatic type, includes a first lever 21 connected at the top by means of a hinge 13a, and, on the shaft, a second lever 20 connected by means of a second hinge 13b, said first and second levers 21, 20 being respectively hinged in the fulcrums 21 a and 20a on the caulking assembly 12 and integral therewith.
  • counterthrust elements 25 each including a helicoidal spring 26.
  • Figure 4 shows a single example of a counterthrust support 30.
  • a slide 32 to which at least two sliding flanges 31 are slidingly connected.
  • the sliding is controlled by a hydraulic circuit 33.
  • the machine object of the present invention may further include graduated or electronic measuring means for the precise adjustment of the forward motion of the heads.
